So I picked up a few of these lately. Usually 1.00 to 1.50 per bottle. So far I'm impressed.

Fruit 2o (http://www.kraftfoods.com/Fruit2o/home.html?channel=4)

Not bad tasting and had a pretty good kick. Less than a dollar a bottle for as much caffeine as a cup of water and a little B12 and B6 0 calories.

O infused water (http://www.obeverages.com/products_infused.asp)

Good taste cost about 1.25 contains Caffeine(more than red bull), Ginseng, guarana, yerba mate, B6, B12, 25 calories. I think this one can be considered an energy drink for sure.

Sunbolt A.M. Energy water. Have not tried but I have 2 bottles and it is made by Nestle waters, B vitamins, Amino acids, Natural caffeine, 6 elctrolytes, chromium, ) calories. Can't find any info on it anywhere? Got 2 bottles at target. Citrus, and Strawberry melon morning. I can't even find it on the nestle water site.:eek:
